Improve this doc

A radio button is a button that can be either checked or unchecked. A user can tap the button to check or uncheck it. It can also be checked from the template using the checked property.

Use an element with a radio-group attribute to group a set of radio buttons. When radio buttons are inside a radio group, exactly one radio button in the group can be checked at any time. If a radio button is not placed in a group, they will all have the ability to be checked at the same time.

See the Angular Forms Docs for more information on forms and input.

Usage

<ion-list radio-group [(ngModel)]="relationship">
  <ion-item>
    <ion-label>Friends</ion-label>

  <ion-item>
